hmmm

24-105 L is 670 g (1.67 pound), the new rumored 24-70 f4L IS is 545 g (1.21 pound). Nearly a half pound lighter. That part would be good.

White box 24-105 can be gotten for maybe $950: a savings $100 (comparing apples to apples, savings of 200 over what the 24-105 USA is going for today at B&H).

If this new lens has better optical performance within its range, better IS, faster AF it might be of interest. Otherwise, the 24-105 is still worth the extra money for the extra range, imho. It all depends on how good the lens turns out to be.

Is this a replacement for the 24-105? Is it going to be the kit lens for the 6D instead of the previously mentioned 6D + 24-105? Or a different kit variant? Will Canon offer the 6D + 24-70 ff4L IS at significantly less than the $2899 pre-order pre-announced for the 6D + 24-105 f4L IS? The retail price difference of the lenses suggests 6D + 24-70f4L IS@ $2699 as an initial retail price.

Would love to see a 35mm f/1.4L II come out with equivalent weather sealing to the 24mm f/1.4L II. IS isn't really a big issue for me at that focal length so I wouldn't be too concerned if that wasn't included.

If the 24-70 f/4L IS has better image quality (and it should since it has a shorter range than the 24-105 f/4L IS), weighs less, costs less and is available as kit lens of 6D, I'll get it in a heartbeat.

The new 50 f/1.4 IS sounds intriguing too.

Now, that's the way to go, Canon. Sony got it all wrong: fabulous sensors, decent cameras but no lenses.

If the 50 IS comes - it will be 2.0 or slower. We seem to be getting slower with IS on new glass.

You're probably basing that on the 24/2.8IS & 28/2.8IS, but you have to remember fast standard primes are much easier (cheaper) to make and more necessary than fast wide primes. If there's any way they can keep it 1.4 and still meet their cost targets I'm sure they will.

I'm really interested in seeing how the 24-70/4 IS performs, and at what price point. If it's reasonably sharp in the center wide open and across the frame by f/8 then it'll be a huge winner in this new era of less expensive full frame bodies.

Hopefully they cut fewer corners on IQ than Nikon did with its new 24-85; the size, weight, and price of that lens are phenomenal but the IQ is arguably worse than the 18-55 crop sensor kit lens... I really want a decent, affordable, reasonably-sized full-frame zoom but nobody seems to be willing to make one. Here's hoping Canon pulls through!

And don't forget that f/2.0 is the fastest that's ever been made with IS, if i'm not mistaken (the EF 200L IS f/2.0). Besides that, there's only a lot of f/2.8 with IS (17-55, 24, 28, 100L, 70-200L, 300L, 400L).So even a 50mm f/2.0 IS might be pushing it (although 50mm is one of the easiest lenses to make fast, so 50mm f/2.0 IS might not be too hard). Alternatively, might we see a videographers' 50mm f/2.8 IS in the same vein as the 24 & 28 f/2.8 IS we got earlier? (and their pricetags?).Noone's mentioned that 50mm f/1.3 rumours from last week either. If we get that, then the door's open for a 50/1.2L replacement at f/1.1 or f/1.0... (we wish)
